7 Claims.

This invention relates to a yielding clamp and, more particularly, to aclamp adapted to hold storm sashes, screen sashes and the like in place.

An object of the invention is to provide a sash clamp whichisessentially simple, eificient and inexpensive.

A further object of the invention is to provide a sash clamp capable ofbeing readily manufactured at low cost, efficient for its purpose andadapted to be readily used without marring the frame member upon whichit is mounted or the sash member which it engages.

The clamp disclosed herein has been designed to be made with a minimumloss of waste material. It is preferably stamped out of resilient sheetmetal. The device is so constructed that it may be easily secured inplace and operated from year to year as sashes and screens are removedor replaced, the design thereof not detracting from the appearance ofthe Window or door frame or scratching or otherwise marring the finishwhen swung into and out of engaging position with the sash.

A still further object of the invention is to provide a sash clamp thatwill securely hold a sash in place, make a tight connection with thewindow frame, and be self-adjustable to permit use with sashes ofdifferent thickness.

It is also an object of the invention to provide a novel type of sashfastener that will readily operate from the interior of the sash to lockthe same closed, thereby defeating any unlawful attempt to remove thesash or open the same if hinged to gain access to the window for thepure pose of unlawful entry into the building.

Further objects and advantages of the invention will be apparent fromthe following detailed specification when taken in connection with theaccompanying drawings which form a part hereof.

It will be mentioned at the outset that the preferred form of fastenerembodying the invention is preferably a metal stamping formed out of asusbtantially semi-circular blank. However, certain essential featuresof the invention may be incorporated in fasteners that may bedifferently formed and not necessarily of the shape of the preferredembodiment. v

The preferred form of fastener illustrated in Figs. 1 to 7, inclusive,is constructed or stamped out of metal of substantially semi-circularshape, as shown in Fig. '7. This fastener, designated A, comprises abase portion l formed along the base edge 2 of blank 3 shown in Fig. '7.In the forming operation, blank 3 may be out along line 4 to form. aresilient finger 5 that is coextensive with said base portion at oneend, whereby the material 6 at the center of the blank may be bentupwardly to provide an upstanding ear 1 capable of being manuallygripped to rotate the fastener about its mounting. Base portion I isdepressed at 8 and perforated at 9 to receive a securing screw H3.Depressing a portion of base about perforation 9 advantageouslyfurnishes a'recess in which the head of securing screw may lie, and atthe same time provide a limited bearing surface between the base portionl and the sash frame or casing upon which the device is mounted.Providing a limited bearing surface in this manner allows the fastenerto be easily rotated about securing screw Hi to overcome sticking andprevent marring of the finish of the frame or casing.

Finger 5 is slightly offset upwardly at H with respect to base portionI, being curved downwardly again at H to bring its tip l3 below theplane of base portion I.

Storm and screen sashes are made in standard stock sizes but they Varyat times in thickness. Recesses in window and door frames adapted toreceive storm and screen sashes will also invariably differ in dimensionaccording to the design and construction of the building. Sash fastenersmust, therefore, be capable of firmly engaging and holding the sashes insuch recesses, notwithstanding these differences in dimension betweenthe depth of the recess and the thickness of the sash.

Figs. 1 and 2 illustrate how the present fastener advantageouslyovercomes the said differences in dimension between the frame recess andthe sash. Finger 5 is provided with an inherent resiliency by virtue ofits curved formation that causes its tip it firmly to bear against thesash whether it lies within the frame or casing recess, as shown inFigs. 2 and 3, or extends beyond the frame or casing recess, as shown inFig. 1. When fastener A is rotated about socuring screw Ill by grippingupstanding ear l and turning the fastener, tip it of finger 5 willreadily flex upwardly and over the edge l5 of the sash 16 if the latterextends beyond the frame or casing i'l. To provide a smooth surface thatin effect will give a cam-like action to tip is of finger 5 when it isforced to ride over a protruding sash edge, like that of i5 in Fig. 1,this tip l3 is bent upwardly at {8 and the side edges it and 28, as wellas the leading edge 21 thereof, are turned over, this being illustratedin detail by the cross section shown in Fig. 6 and taken along line 65in Fig. 5 through tip l3. Hence, the leading ledge 25 on tip l3 will notcatch or dig into or otherwise mar edge of sash it but will ridethereover to bring this tip it of finger 5 over and upon the surface ofsash it to firmly bear thereagainst and hold this sash tightly inposition against frame ll.

Fastener A may be secured upon frame ll at different distances from thesash opening edge. I have illustrated in Figs. 1 and 2 a portion of baseI also riding over edge 5 and bearing against sash l6, if so desired. Toprevent edge 2 of base portion i from cutting into or catching upon edgel5 of sash 53, an upstanding lip i? may be formed therealong.

If sash i6 is of less thickness than the depth of the frame or casingrecess, as illustrated in Fig. 2, finger 5 will cause its tip 13 toreadily engage and bear against the sash to hold it firmly in position.It will be noted that fastener A may be formed out of a substantiallysemicircular blank, as pointed out above, without incurring any wastematerial, and consequently, when it is formed out of a continuous stripthe waste material between successive fasteners will be reduced to aminimum. Finger 5 is given an inherent resiliency by virtue of itsformation that causes its tip to exert sufficient pressure against thesash it engages whereby such sash is firmly held in position. Fastener Amay be easily operated and readily mounted on the frame withoutdetracting from the appearance of the window opening. Its operation willnot mar or scratch the finish of the frame or sash.

The variant embodiments B, C, D and E, illustrated in Figs. 8 to 11,inclusive, incorporate certain essential features considered to bewithin the scope of the invention. The fastener B shown in Fig. 8includes a base 22 that is perforated to receive a securing screw 23 formounting the fastener, a resilient finger 24 and an upturned ear 25adapted to be manually gripped to swing this fastener about securingscrew 23 whereby the resilient tip of finger 2 5 may be moved over andupon member 26 to bear resiliently thereagainst in order to hold it inposition. Upturned ear 25 lies between base 22 and finger 24. Thestructure C, illustrated in Fig. 9, is substantially the same asillustrated in Fig. 8 except that base 2'! is disposed substantiallycloser to resilient finger 28 and this resilient finger is adapted tohave its tip bent at right angles so as to lie parallel to the edge ofthe member 29 which it holds in position. The fastener D illustrated inFig. 10 is substantially the same as the preferred embodimentillustrated in Figs. 1 to 7, inclusive. Instead of upturned ear 'i inthe preferred embodiment being formed along the inner edge 29 of thebase, the outer edge is formed to provide this upturned ear l. Fastenershown in Fig. 11, has its resilient finger all, base portion 33 andupturned ear 35 arranged in slightly different relation, but thesecomponent parts are so associated with each other in a fastenerstructure of this type as to accomplish substantially the same resultsas illustrated in the previous embodiments. Resilient finger 3B issomewhat curved to bring its tip 3! prac tically parallel to the edge ofthe member 32 which it holds in position while base is formed at theopposite end of this finger with upturned ear 34 along the edge of base33.

Frequently, fasteners of the type heretofore described cannot .beconveniently used along the top rail of the window frame or casing. InFigs. 14 and 15, a fastener 35 is illustrated that is simple and formedof a rectangular piece of metal, and is so shaped as to have base 35perforated at 3'! for a securing element, and a resilient finger 38 ofV-shape that is so bent that the apex 39 of the V may bear against thesash to hold it in position. To illustrate, Fig. 12 shows two fasteners36 mounted upon the upper rail of a window frame or casing. Resilientfinger 38 is allowed to protrude below the lower edge of this upperrail. The sash is moved upwardly in position so that the upper edgethereof will be moved under the outer leg til of finger 38. Leg 413 isbent outwardly to allow the upper edge of the sash to be moved intoposition within the frame without any interference whereby the finger 38will securely hold the sash in position.

In order to lock the sashinteriorly to prevent unauthorized access tothe window 'by removing the sash on the outside of the building, aslotted bracket 45 may be attached at any suitable location within thewindow frame, the member 46 shown in Fig. 17 representing, for example,the usual stop strip of a window frame. Bracket 45 may have its legs 41and 48 of such angular relation as may be necessary in view of themanner in which the bracket must be mounted in order to properlyposition leg 4'! having slot 49 therein. A second bracket 5! provided inthe form of a strap having a central offset portion 52 may be attachedto the inside of sash member 53. Offset portion 52 is perforated toreceive a bolt 54. The head of bolt 54 lies within the recess providedby offset 52 whereby the bolt will be held in position and is not freeto drop out of place when bracket 5! is attached against a sash member.Bracket 5| is so located upon sash member 53 that when this sash memberis brought to closed position against stop 46, the

shank of bolt 55- may be dropped into slot 49.

Slot A9 is slightly cut away at so that after bolt 54 is movedtransversely into slot 49, it may be raised slightly to move into thecut-away nortion 50. A nut 55 may then be used to lock bolt 54 in thisposition.

Hence, there is disclosed in the present invention a complete set ofstorm or screen sash fasteners for mounting, securing and locking thesash members in proper position within a window or door frame.

Without further elaboration, the foregoing will so fully explain thegist of my invention that others may, by applying current knowledge,readily adopt the same for use under varying conditions of service,without eliminating certain features, which may properly be said toconstitute the essential items of novelty involved, which items areintended to be defined and secured to me by the following claims.
